IMPROVE!) SOLE-CHANNLLING- AND FEATHER-EDG-ING- The Schedule referred toin these Letters Patent and making part of the same.

To all whom it concern: 1 y j yBe it known that I,`HENRY S. VROOMAN, ofBoston, in the county of Suffolk, and State of Massachusetts,

, have inventedV Improvements in Sole-Ohannelling or l Feather-EdgingMachines; and `I do 'herebydeclare that the following, taken inconnection with thedrawings which' accompany and -form 'part of thisspeciiica tion, is a description of able those skilled-in the art topractise it. p,

This invention has particular reference to so ar' ranging anordinarychannelling-machine, for` channelling 'the soles of boots andshoes, preparatory to sewing the uppers thereto, that the guide for` theedge of the sole vmay be adjusted, to vary the distance of the edge ofthe sole, or the width of a chamfer at the edge of the sole; also, toproviding a rest for the under side of the sole in the intermediatespace between the edge-guide and the toothedfeed-Wheel, and to -soconstructing this rest that a knife attached to the upper portion or armof the machine will pass down below the sole, and skive,

chamfer, or bevel the under surface at theedge; also, to a provision foradjustment of the upper smooth presser or feed-wheel horizontally, withreference to the edge-guide, and tothe arm by which it is supporteedge-guide for the sole I regard as preferable, either for ordinarychannelling on the upper surface` of the sole, or skiving the `undersurface, to the provisionI have already patented, January'l, 1867, formoving the arm horizontally, to adjust the cutters in theirrelation tothe edge-guide,

ter or cutters to sole.

A shows a sideand sectional elevation of jthe feed- `Wheels and adjacentmechanism.`

B is a section" ou the line :c x.

vO is a plan ofthe lower feed-wheel, the edge-rest, and the edge-guide.adenotesfvthe front post of i the machine, in which is the bearing@ forthe shaft of the lever or toothed `feed-wheel c.

jd is the movable arm, carrying the pin orshaft of the upperorsmooth-faced feed-wheel e, the arm .dropthe surface of the upper rollping by its weight, until my invention sufficient to eninventionrelating to a movable Y in that the same resultcan4 be produced withoutchanging the relation of the cut# the toothed feed-wheel carryingthe Myinvention is not,'broadly, in such an arrange` ment of mechanism asshall causethe sole to be bevback, the wheel may be is at suchv distancefrom the adjacent surface of the l lower roll as to cause the upperwheel to-be raised by the insertion of a sole between the wheels, theweight of the'upper wheel and the arm d, or downward'pressure brought tobear upon the arm, causing the sole to be pressed against Vthe teeth ofthe wheel c, so as to insure its feed-movement to the action of thecutter. f denotes the rest which supports the edge of the sole to bebevelled or skived.

.In the ordinary andwell-knownMcKay channellers, i as the cutter worksupon th upper surface of the sole, the lower surface of the .soleadjacent to the edge is supported up'on a smooth rim `which is made uponthe toothed feed-wheel beyond the teeth, the sole-next to its edge being'supported upon this surface. It will be obvious, however,` that thewheel cannot be so made in this machine, because the bevelling-cuttermust oc-N'Vf cupy the space just below the edge of the sole.v

I therefore make'the lower feed-wheel narrow, and

project from the post a'a stationary rest-plate, j; which the sole isheld as it is fed to the action ofthe cutter,

and

its position determining the vwidth of the skiving, l

so e,

the distance-of the channel from the edge ofthe when any kind 'ofchannelling-cutter is used.

' To vary the width of the skiving, or the distance of the channel fromthe sole-edge, without moving the rest, this guide is made movable,andadjustable in position upon the rest-plate,-by means of a` slot andscrew, lc. j Y; The guide is lslotted,-as seen at l, to allow the shankof the cutter to drop through it. s

To adj ust ythe upper feed-wheel to correspond to theV position of theedge-guide, that is to say, to keep the wheel up to the guide, andwithout moving the arm', I mount the'wheel on a screw-pin, m, on whichit turns loosely, the wheel, in its rotation, beingconned y between thehead, n, of the screw and a collar, o, and screwing into the arm d, asshown at A.

By turning the screw shown', the wheel is moved to I ward or from theguide, and, as the guide is moved moved up to it, so as to bear uponvthe 'whole upper surface opposite 'to which the cutter h is acting. Itwill be obvious that a ,smooth feed-roll, and adjustable horizontallywithin the arm, and fastened in anyone position by a setscrew, may beused instead of the screw m. y By these means, it will readily be seenthat, while the cutter is varranged so as to skive the lower surface ofthe sole fed between the wheels, the sole adjacent vto the edge issupported, and prevented from bending down, and provision is made forguiding the edge of plain pin, the

the sole, and for adjustment of the edge-guide, (to vary the width ofthe skiving, or the distance of a channel from the edge,) and forthepressure upon the upper surface to correspond with such movements ofthe edge-guide.

I claim, in combination with the smooth-surfaced upper feed-wheel, thetoothed-surfaced lower feedwheel, and the cutter or cutters, arranged tooperate upon either surface of the sole, a stationary rest-plate,

Y for supporting the sole andedge to be skived or channeiled,substantially as shown and described.

Also, so constructing this rest-plate that the skiving-cutter or itsshank can pass through or by the plate from the arm d, so as to bringthe cutter to the under surface of the sole, substantially as described.
